CVE-2026-110873 · Heym 0.0.55 before 0.0.121 Credential Theft via error_workflow_id Field
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Heym from 0.0.55 before 0.0.121 contains a privilege escalation vulnerability that allows shared collaborators to overwrite a workflow's error_workflow_id because the field is missing from OWNER_ONLY_EXECUTION_FIELDS. Attackers can point the error workflow to their own workflow with an HTTP node, and when the parent workflow errors the owner's decrypted credentials are injected and exfiltrated.
